What is mPPE FR-V0?
mPPE FR-V0 is mPPE in the FR-V0 grade — phosphate-ester FR grade for enclosures, breakers, PV junction boxes and battery components requiring V-0 at 1.5 mm. mPPE FR-V0 has a yield strength of 58 MPa (8.41 ksi) and a tensile strength of 55 MPa (7.98 ksi) — stronger than 66% of polymer grades. Elongation at break is 40% and the elastic modulus is 2.4 GPa (0.348 Msi). mPPE FR-V0 has a density of 1.1 g/cm³ (0.0397 lb/in³), lighter than 66% of polymer grades. Its glass-transition temperature is 145°C (293 °F). UNF is the default condition FabDigit quotes; FR-V0 is available on request or by drawing note.
Advantages

Working with mPPE FR-V0
Is mPPE easy to machine?
Machines cleanly with sharp positive-rake tools and air cooling; avoid aromatic/chlorinated coolants which cause stress cracking, and anneal 2 h at ~110 °C before tight-tolerance finishing.
Can mPPE be welded?
Excellent for ultrasonic, vibration and hot-plate welding; solvent bonding with chlorinated solvents or adhesives also works, but hot-gas welding needs careful temperature control to avoid PS-phase degradation.
Can mPPE be formed, bent or molded?
Dry 2–4 h at 100–110 °C, mold at 260–300 °C melt with 60–110 °C tool; amorphous shrinkage of ~0.5–0.7 % is low and isotropic, giving very stable tolerances.
What surface finishes work on mPPE?
Takes paint, hot stamping and electroless plating well after standard etch/primer steps; UV-absorbing paint or pigment is recommended for outdoor use since unstabilized mPPE yellows.
mPPE chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

mPPE FR-V0 — frequently asked
What is mPPE FR-V0 used for?
mPPE FR-V0 is typically used for electrical enclosures and connectors, automotive instrument panels, plumbing fittings, business machine housings and HVAC components. In short: most dimensionally stable amorphous resin; lowest-density engineering thermoplastic; inherently flame-retardant blend.
What is the yield strength of mPPE FR-V0?
mPPE FR-V0 has a typical yield strength of 58 MPa (8.41 ksi) and a tensile strength of 55 MPa (7.98 ksi) — stronger than 66% of polymer grades. Strength varies by condition: see the 12 listed tempers.
Is mPPE FR-V0 easy to machine?
Reasonably — machinability is rated good (65/100, better than 66% of polymer grades). Machines cleanly with sharp positive-rake tools and air cooling; avoid aromatic/chlorinated coolants which cause stress cracking, and anneal 2 h at ~110 °C before tight-tolerance finishing.
Can mPPE FR-V0 be welded?
Yes — weldability is rated good (65/100). Excellent for ultrasonic, vibration and hot-plate welding; solvent bonding with chlorinated solvents or adhesives also works, but hot-gas welding needs careful temperature control to avoid PS-phase degradation.
What surface finishes work on mPPE FR-V0?
Takes paint, hot stamping and electroless plating well after standard etch/primer steps; UV-absorbing paint or pigment is recommended for outdoor use since unstabilized mPPE yellows.
Can mPPE FR-V0 be formed, bent or molded?
Dry 2–4 h at 100–110 °C, mold at 260–300 °C melt with 60–110 °C tool; amorphous shrinkage of ~0.5–0.7 % is low and isotropic, giving very stable tolerances.
What is the maximum service temperature of mPPE FR-V0?
mPPE FR-V0 is rated for continuous use to about 90°C (194 °F), and briefly to 130°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between mPPE UNF and mPPE SF?
UNF is the default condition — default choice for housings, water-contact parts and dielectric components needing toughness and dimensional stability. SF: chemically blown thick-wall grade for large, stiff, low-density enclosures and pallets. Yield strength is 58 MPa in UNF versus 32 MPa in SF.
